How to start a blog?

I created this blog several weeks ago intending to record all my outdoor adventures, trips, and anything else of that nature. I haven't started it, not because I haven't had any adventures (I've had plenty) but honestly I just didn't know how to start the blog. Do I introduce myself or something? eh. So I guess I'll just dive in. Hey whats up? My names Melissa and I like to play outside.
